PROBLEM TO BE SOLVED: To reduce the case where ROP(raster operation) becomes incorrect. SOLUTION: An object determining section 103 determines the type of write object and calls a suitable LUT setting section 104 or 105. Depending on a color conversion LUT set by a called LUT setting section 104 or 105, a color converting section 106 converts the color of the write object. The color converted write object is written at a rasterize section 107 and when the LUT setting section 105 is called at the object determining section 103, a raster operation deciding section 108 calls a suitable LUT setting section 104 or 105 depending on the ROP(raster operation) of the write object.
